Answer 3

what do you mean by less than or greater to

Answer 4

So, you just plug it in?

Answer 5

This!

Answer 6

Answer 7

try (1;10) you get 10<-4 and 10<-5 in this case it doesn't make sense try the next one

Answer 8

Ok, thx for helping me! what is the next?

I don't thi the nex tis right. :(

Answer 10

try (-1;10) 10<-6 and 10<-3 this also doesn't make sense

Answer 11

try (10;1) 1<5 and 1<-14 first one makes sense but second doesn't so it must be the last one but we should verify

-10<-4 and -10<-3 which makes sense right?

Answer 13

I guess, so it is d?

yup negative ten is smaller that -4 and negative ten is smaller that negative three so both statements are true and the answer is d
